mechanism:
None (1) ·
5-HT1A agonist, 5-HT2A antagonist, with weaker activity at D4 and other receptors. Net effect involves enhanced prefrontal dopaminergic/noradrenergic tone with decreased serotonergic inhibition of sexual desire. (1) ·
'"`UNIQ--vote-000000B6-QINU`"' Active metabolite EXP3174 is ~10-40-fold more potent than the parent and accounts for most of the antihypertensive effect; CYP2C9 polymorphism affects conversion'"`UNIQ--ref-000000B7-QINU`"'. (1) ·
'"`UNIQ--vote-00000391-QINU`"' Minimal CYP metabolism; mostly renally cleared unchanged. Cetirizine is the active racemate; levocetirizine is the active R-enantiomer marketed separately'"`UNIQ--ref-00000392-QINU`"'. (1) ·
'"`UNIQ--vote-0000061E-QINU`"' Less reliably anticholinergic than first-generation H1s; minimal antiemetic effect. Desloratadine (Clarinex) is the active enantiomer-of-metabolite version marketed as a Rx alternative. (1) ·
'"`UNIQ--vote-00000762-QINU`"' Largely renally cleared, hence the eGFR-tiered dosing. Rare but well-documented signals: acute pancreatitis (uncertain causal contribution), severe joint pain, and bullous pemphigoid (class effect, especially in older Asian patients)'"`UNIQ--ref-00000763-QINU`"'. (1) ·
'"`UNIQ--vote-0000104D-QINU`"' Adequate hydration is at least as important as the drug in producing the expectorant effect clinically. Used in combination with dextromethorphan, decongestants, or antihistamines in many proprietary OTC cold preparations. (1)
